If, like a lot of energy-zapped people, you have trouble falling asleep, you may reach for a daily glass of wine to help you unwind. But, according to Phillips, having more than one alcoholic drink a day -- particularly if you're a woman -- can make you feel more tired than if you had just stuck with water.

Not only does alcohol have a dehydrating effect, which makes you feel tired, but it drains your body of magnesium. "Even slightly low levels of magnesium can cause fatigue," says Phillips, who explains that your body excretes magnesium when it metabolizes alcohol.

And while alcohol might help you knock out quicker, it makes you sleep more fitfully, robbing you of precious REM, or deep, sleep -- so you wake up feeling even more exhausted.

When it comes to breakfast, not all meals are created equal. To get the most energy-boosting benefits from your morning meal, Phillips recommends kicking off your day with a combination of complex carbohydrates and protein.

Foods rich in complex carbohydrates -- think fruits, vegetables and whole grains -- contain sugars that are a "readily usable source of energy for our cells," says Phillips. Unlike simple sugars -- the kinds found in foods containing glucose, sucrose, fructose or any other ingredient ending in "ose" -- the sugars found in complex carbohydrates allow for a slow and steady rise in blood sugar and, in turn, energy. That means you won't get that crazy sugar high and inevitable crash that you might get with eating, say, a supersweet breakfast cereal.

And as for proteins, Phillips says they are "important in manufacturing adenosine triphosphate (ATP), which is what we use for energy."

Some easy breakfast options: peanut butter toast and an apple, Greek yogurt with berries and whole-grain granola or oatmeal with walnuts and raisins.

Looks like your mom may have had a good reason for telling you to sit up straight all those years. "Poor posture doesn't just make you look like you're tired, it can actually make you feel tired," says Phillips. If your body isn't properly aligned, she explains, you can put excess strain on your back and hips, which means your body has to work harder and you end up feeling more tired. A slumped-over position also lowers mood -- and self-esteem, which won't exactly put pep back in your step.

To avoid that mid-afternoon slump in both posture and energy levels, make a conscious effort to check your posture whether you're sitting or standing. "Your shoulders should be back with your blades almost touching -- as close to touching as you can get them," advises Phillips. You should also be mindful of having your head jut too far forward or back.

If you're having trouble focusing but fear you might have to take a trip to the ER if you down another energy drink, a simple stretch might help. "Any position that puts your head below your waist increases blood flow to your brain and makes you more alert," says Phillips. "So even something as simple as standing up and touching your toes for 10 seconds can help improve your alertness." Desk-bound workers might appreciate the fact that they can pull off this move while sitting down.

Forget waking up and smelling the roses. If you want to kick start your day, Phillips suggests getting a whiff of peppermint, rosemary or jasmine, which have all been shown to increase alertness.

For an easy way to incorporate this energy-enhancing aromatherapy into your life, she recommends using products with notes of the stimulating scents during your morning shower. Try lathering up with Juara Tiare Jasmine Tea Bath & Shower Gel and then moisturizing with an invigorating peppermint moisturizer, like Bath & Body Works Triple Moisture Body Cream Twisted Peppermint cream.
